Nitrogened metabolites in golden hamster fed with proteic diets based on Eisenia spp. meal

Abstract:

Content of total protein (PT), albumin (Alb), globulins (Glb), urea (U), uric acid (AU), creatinine (Ct) and transaminase levels (oxalacetic-glutamic (TGO) and piruvic-glutamic (TGP)) was evaluated in the blood plasm of golden hamster (Mesocrisetus auratus L.), fed diets (crude protein; PB= 13.5- 19.6%) with red worm (HL) (Eisenia spp.) meal and two conventional feeds (Conejarina®; PB= 11.4% and Ratarina®; PB= 21.1%). The PT, Alb, Glb and Ct concentration oscillated among 5-6, 2- 3, 2-3 g/dL y 0,3-0,4 mg/dL, respectively, no significant differences among the treatments in the assay were observed (p>0.05). In the assay the U and AU content fluctuated between 23-101 y 3-9 mg/dL, respectively; according to the PB level, HL inclusion and measurement time. The transaminase levels were high and variables during the second week of assay, according to the proteic level diets (TGO: 101-699 y TGP: 54-890 UI/ L). The seric PT, Glb, Alb and Ct content were independent of PB diets and HL proportion, while the U (R2= 0.509*), TGO (R2= 0.661**) and TGP (R2= 0.524*) level were related with proteic level of diets, and the U (R2= 0.502*) and AU (R2= 0.531*) contents with the HL inclusion. The HL addition in 24, 27 and 30% for making formulated proteic diets to M. auratus cause significant variation in the normal values of U, AU and transaminases.
